To all whom it may concern:

Be it known that I, GUSTAVUS AnoLrHUs TUERK, n citizen of the United States of America. residing at the city of Kitchener, in the county of Waterloo, Province of Uh turio, Canada, have invented a new and useful Improvement in Internal-Combustion Engines, of which the following is a spec1- fication.

My invention relates to improvements in internal combustion engines, and more par ticulnrly to engines of the two cycle type. It consists primarily in the provision of a sleeve piston mounted on s stationery ennulnr guide so that a. compression chamber is formed between the heed of the said guide and the underside of the head of the sleeve piston. 0n the upper side of the said sleeve piston I secure a hollow deflector of necessary height to give the desired compression in the cylinder.

'One of the objects of my invention is to provide means for obtaining greater compression than is possible with the usual two cycle engine at present in use.

Another object of my invention is to obviate the necessity of the mixture being introduced into the crank case.

A further object of my invention is to provide a. light and hollow deflector of the re quired depth to keep the piston head c001,.

and which will give the desired amount of compression. And further to render it possible for the said deflector to be easily changed so that the amount of the compression can be readily varied to suit low grades of fuel when desired.

7 With these and other objects in View my invention. consists in certain novel construction and. combination of parts hereinafter more fully described and claimed.

In the accompanying drawings similar numerals refer to similar parts throughout all the views, in which:

Figure 1 shows a sectional elevation of my engine.

Figure 2 is a front view partly in section and partly in elevation.

Figure 3 represents an inverted plan of my deflector.

Figure 4 is a portion of the inside wall of the cylinder. v

igures 5 and 6 show side elevations of my sleeve piston and stationary annular guide respectively.

Figure is a cross section on the line E's-4 of Figure 2..

Referring more particularly to drswings 1 designates the cylinder casing mounted on any desired form of crank cese stationary annular guide 3 I prefer to so cure to u circular plate 4-, the latter can however be made integral with the guide if preferred. 0n one side of the cylinder 1, I provide a trnnsfer chernher 5 into which communication is made from the can huretter of any known make indicated it 6. preferably-through the ball valve 2'. in the Wall of the cylinder 1, I arrange lower, centrsh and upper ports 8, 8 and 8 respec tively. And onto the piston heed 16 ll secure a deflector 9 so designed that on sir space 9 is formed thereunder, and 1 provide said deflector With an inclined face 9 opposite the inlet ports 8 11 is the exhaust port, the upper portion of which ex tends above the top of; the inlet ports 8". 12 is a Water space with suitable connections 12 and 12 and 13 indicates the spark plug.

.The piston 10 I furnish with rings 10.

and towards its lower end I arrange studs 10 to carry the gudgeon pin 14%, to which latter the connecting rod 15 is pivotelly so cured. ltlecesses 1 are provided in the lower portion of the cylinder casing 1 to allow The ill?

the studs vl0 to move therein, and similnrly slots 3 are arranged in the sides of the en nular guide 3 to allow movement of the gudgeon pin 14. On the outer tsce off the annular guide 3 I supply piston rings 8*. Q.

And in the side of my sleeve piston 10 ll provide an inlet 10 and also a. vertical pns- Sage 10".

' I find that if I provide the annular guide 3 with a series of holes 3, and an irregular surface 3 I attain three objects; the Weight of the guide is considerably lessened; the friction between it and the inside circumference of my sleeve piston 10 is greatly reduced, and the irregu or surface holds luhrication better. Similarly I refer to provide holes throughout the vial of my sleeve piston 10 as indicated at we I fihd thnt'it decreases the Weight, lessens hearing sur face and therefore the friction, and aids lubrication.

The ball valve 7' shown in Figure 1 my of ooursebe changed for one of another design if it is so desired. My valve consists or a disc 7 provided, with holes 7 on each lit? re'sis bail 7 1103.6. in piace by aspring 7" which in turn is uawn by the cap 7.
